Baby cold and cough: caring for your baby at home
A blocked nose, a rasping little cough, a baby who cannot quite settle to feed or sleep: colds are unsettling for parents and uncomfortable for babies. The good news is that most colds resolve on their own within one to two weeks, and there is a great deal you can do at home to keep your baby comfortable while they recover. This guide draws entirely on NHS guidance to help you understand what to expect, what actually helps, and the specific signs that mean your baby needs to be seen by a doctor.
What causes a cold and how does it spread?
The common cold is a viral infection of the nose and throat. It spreads very easily between people through close contact, through droplets produced when an infected person coughs or sneezes, and through touching contaminated surfaces and then touching the face. Babies are particularly vulnerable in their first year because their immune systems are still building up experience of these viruses. Good hand washing is one of the most effective ways to slow the spread within a household, and keeping used tissues away from your baby's reach is also important.
How symptoms develop
Symptoms do not appear all at once. They tend to build up gradually over two to three days. In babies, you may notice:
- A blocked or runny nose, which can make feeding much harder because babies breathe through their noses
- Sneezing more than usual
- A cough, which is often the body's way of clearing mucus from the throat
- A raised temperature
- Irritability and difficulty settling, particularly around feed times and sleep
- Tiredness and low energy
Babies with a cold tend to remain contagious until all of their symptoms have fully cleared, which can take longer than in adults. It is worth letting nursery, childminders, or other carers know so they can take precautions.
Safe home care for babies with a cold
There is no medicine that cures a cold. The goal of home care is to keep your baby as comfortable as possible while their body does the work. The following approaches are supported by NHS guidance.
Keep fluids going
Hydration is one of the most important things during a cold. For babies under six months, this means continuing to breastfeed or bottle-feed as usual. Breast milk in particular contains antibodies that support your baby's immune response. Older babies can also have small amounts of cooled boiled water alongside their usual milk. Never offer hot drinks to young babies or children.
Offer plenty of rest
Your baby's body is working hard. Short, frequent feeds combined with extra rest periods can help. If your baby is sleeping more than usual, that is normal during illness.
Consider a vapour rub designed for babies
NHS guidance notes that vapour rubs can be used for babies to ease congestion. Always check the product is suitable for your baby's age before using it, and follow the instructions carefully. Ask a pharmacist if you are unsure which product is appropriate.
Use a warm shower to ease breathing
Sitting with your baby in a bathroom while a warm shower runs can help loosen congestion through the steam in the air. This is safer than a bowl of hot water, which NHS guidance specifically advises against because of the risk of scalding.
Pain and fever relief
If your baby has a raised temperature or appears to be in discomfort, age-appropriate paracetamol or ibuprofen can help. A pharmacist can advise on the correct dose for your baby's age and weight. Always follow the dosing instructions on the packaging.
What to avoid
Some things that feel natural to reach for are not safe for babies in this age group. Being aware of these helps you avoid accidental harm.
- Honey: Must not be given to babies under 12 months under any circumstances, including as a cold remedy. This applies to honey in drinks as well as on its own.
- Hot lemon and honey drinks: The NHS suggests this as a soothing option for adults, but it is not appropriate for young babies both because of the honey and because of the temperature risk.
- Decongestant nasal sprays or drops: These are not suitable for children under six years old.
- Steam from a hot water bowl: As noted above, this carries a scalding risk and NHS guidance advises against it for babies and young children.
- Antibiotics: Colds are caused by viruses, not bacteria. Antibiotics do not treat viral infections and a GP will not prescribe them for an uncomplicated cold.
When to seek medical help
Most colds do not need a doctor visit. However, there are clear signs that your baby needs to be assessed. Contact your GP, call 111, or seek urgent help if:
- Your baby has a high temperature that has not come down after three days
- Your baby's symptoms are getting noticeably worse rather than gradually improving
- Your baby has not improved at all after ten days
- A cough lasts longer than three weeks
- Your baby is showing signs of difficulty breathing, such as rapid breathing, flared nostrils, or a visible effort to breathe
- Your baby has chest pain or seems very unwell
- Your baby has a condition that affects their immune system, or another underlying health condition
If you are ever in doubt, it is always right to seek advice. Health visitors, pharmacists, 111, and your GP are all there to help.
Frequently asked questions
How long does a cold last in a baby?
Most colds clear up within one to two weeks. In babies and young children, symptoms can sometimes linger a little longer than they do in adults, and babies may remain contagious until all symptoms have fully resolved.
Can I give my baby honey to soothe a cough?
No. Honey must not be given to babies under 12 months. It is not safe for this age group regardless of the reason it is being offered.
Can I use steam to help my baby breathe more easily?
NHS guidance advises against sitting babies or young children over a bowl of hot water for steam inhalation because of the risk of scalding. A warm shower running in the bathroom while you sit nearby with your baby is a safer alternative.
When should I call the doctor about my baby's cold?
Seek medical advice if your baby has a high temperature that does not come down after three days, if their symptoms are getting noticeably worse, if a cough persists beyond three weeks, or if symptoms have not improved at all after ten days. Also seek help if your baby has difficulty breathing or seems very unwell.
Are decongestant sprays safe for babies?
Decongestant nasal sprays are not suitable for children under six years old. Always speak to a pharmacist or GP before giving any medicine to a baby.
